OVER-CENTER
NOTE: Before performing this procedure, the worm
bearing preload adjustment must be performed.
(1) Rotate the stub shaft with a 12 point socket
from stop to stop and count the number of turns.
(2) Starting at either stop, turn the stub shaft
back 1/2 the total number of turns. This is the center
of the gear travel (Fig. 27).
(3) Place the torque wrench in the vertical position
on the stub shaft. Rotate the wrench 45 degrees each
side of the center and record the highest rotational
torque in this range (Fig. 28). This is the Over-Cen-
ter Rotating Torque.
NOTE: The stub shaft must rotate smoothly without
sticking or binding.
(4) Rotate the stud shaft between 90° and 180° to
the left of center and record the left off-center pre-
load. Repeat this to the right of center and record the
right off-center preload. The average of these two
recorded readings is the Preload Rotating Torque.
(5) The Over-Center Rotating Torque should be
0.40-0.70 N·m (3-7 in. lbs.) higher than the Preload
Rotating Torque.
(6) If an adjustment to the Over-Center Rotating
Torque is necessary, first loosen the adjuster lock
nut. Then turn the pitman shaft adjuster screw back
(COUNTERCLOCKWISE) until fully extended, then
turn back in (CLOCKWISE) one full turn.
(7) Remeasure Over-Center Rotating Torque. If
necessary turn the adjuster screw and repeat mea-

surement until correct Over-Center Rotating Torque
is reached.
NOTE: To increase the Over-Center Rotating Torque
turn the screw CLOCKWISE.
(8) Prevent the adjuster screw from turning while
tightening adjuster lock nut. Tighten the adjuster
lock nut to 49 N·m (36 ft. lbs.).

DESCRIPTION AND OPERATION
STEERING LINKAGE
DESCRIPTION
The steering linkage consist of a pitman arm, drag
link, tie rod, tie rod ends and a steering damper (Fig.
1) and (Fig. 2). The service procedures and torque
specifications are the same for LHD and RHD vehi-
cles.
CAUTION: Components attached with a nut and
cotter pin must be torqued to specification. Then if
the slot in the nut does not line up with the cotter
pin hole, tighten nut until it is aligned. Never loosen
the nut to align the cotter pin hole.

SERVICE PROCEDURES
STEERING LINKAGE
The tie rod end and ball stud seals should be
inspected during all oil changes. If a seal is damaged,
it should be replaced. Before installing a new seal,
inspect ball stud at the throat opening. Check for
lubricant loss, contamination, ball stud wear or cor-
rosion. If these conditions exist, replace the tie rod. A
replacement seal can be installed if lubricant is in
good condition. Otherwise, a complete replacement
ball stud end should be installed.
CAUTION: If any steering components are replaced
or serviced an alignment must be performed, to
ensure the vehicle meets all alignment specifica-
tions.
CAUTION: Components attached with a nut and
cotter pin must be torqued to specification. Then if
the slot in the nut does not line up with the cotter
pin hole, tighten nut until it is aligned. Never loosen
the nut to align the cotter pin hole.
REMOVAL AND INSTALLATION
TIE ROD
CAUTION: Use a Puller tool C-3894-A for tie rod
removal. Failure to use this tool could damage the
ball stud and seal (Fig. 3).
REMOVAL
(1) Remove the cotter pins and nuts at the tie rod
ball studs and drag link.
(2) Loosen the ball studs with a puller tool to
remove the tie rod.
(3) Loosen clamp bolts and unthread the tie rod
end from the tube.
INSTALLATION
(1) Thread the tie rod end into the tube and posi-
tion the clamp to it’s original position (Fig. 4).
Tighten the clamp bolts to 27 N·m (20 ft. lbs.).
(2) Install the tie rod on the drag link and steering
knuckle. Install the retaining nuts.
(3) Tighten the ball stud nut on the steering
knuckle to 47 N·m (35 ft. lbs.). Tighten the ball stud
nut to drag link to 74 N·m (55 ft. lbs.). Install new
cotter pins.
